The largest glaciers are continental ice sheets or icecaps, enormous masses (greater than 50,000 square kilometers [12 million acres]) of ice found only in Antarctica and Greenland. These sheets contain vast quantities of fresh water.
What is the world’s largest glacier called?
The largest glacier in the world is the Lambert-Fisher Glacier in Antarctica. At 400 kilometers (250 miles) long, and up to 100 kilometers (60 miles) wide, this ice stream alone drains about 8 percent of the Antarctic Ice Sheet. Antarctic ice is up to 4.7 kilometers (3 miles) thick in some areas.
Which is the second largest glacier?
Closeted in a lap of an archetypal U-shaped glacier valley with the Saltoro Hills to the west and Karakoram Range to the east in the Ladakh District of the state of Jammu and Kashmir, the Siachen Glacier is the longest (76 km) glacier in Himalaya and the second longest glacier in the world outside the Polar Regions.
What are the 5 types of glaciers?

What are the 2 types of glaciers?
There are two main types of glaciers: continental glaciers and alpine glaciers. Latitude, topography, and global and regional climate patterns are important controls on the distribution and size of these glaciers.
Which country has no glaciers?
Without glaciers, one resident quipped, Iceland is “just land.”
Which is the slowest glacier in the world?
The slowest glaciers in the world are cold-based glaciers, which often only move very slowly. These glaciers are frozen to their bed and have little basal sliding.
Which country has most glaciers?
Pakistan has more glaciers than almost anywhere on Earth.
Why are glaciers so blue?
Glacier ice is blue because the red (long wavelengths) part of white light is absorbed by ice and the blue (short wavelengths) light is transmitted and scattered. The longer the path light travels in ice, the more blue it appears.

What is the most powerful erosive force?
THE FORCES OF EROSION: WATER, GLACIERS, AND WIND
But the most powerful erosive force on earth is not wind but water, which causes erosion in its solid form — ice-and as a liquid. Water in its liquid form causes erosion in many ways. Streams — from tiny creeks to huge rivers — carry tons of eroded earth every year.
What causes glaciers to move?
Glaciers move by a combination of (1) deformation of the ice itself and (2) motion at the glacier base. … This means a glacier can flow up hills beneath the ice as long as the ice surface is still sloping downward. Because of this, glaciers are able to flow out of bowl-like cirques and overdeepenings in the landscape.
What is a growing glacier called?
The processes and features caused by or related to glaciers are referred to as glacial. The process of glacier establishment, growth and flow is called glaciation. The corresponding area of study is called glaciology.
